Would taking an internship at a CPA firm be good?

I am a high school student, and am considering taking an interview at a CPA firm, it provides auditing, taxation, business management and outsourced accounting services to many businesses. The business is recognized as a top 25 firm in the DC area. I am doing this to help me get into a good college and make some money. Would this job be really boring? Would it be worth it over the summer?
